I figured out the problem. My shutter speed was set too low. Turns out it needs to be double the frame rate in order to achieve a smooth motion when interpreted to 24 fps. Should have thought of that before I shot. Oh well. Lesson learned.
Since this has worked with Canon footage in the past, my best suggestion would be to import your a7s footage into a 59.94 fps sequence in Premiere, export that sequence (in 59.94) in a universal format like H.264, then re-import that clip to Premiere and try slowing it down to 23.976. My guess is that Premiere isn't playing nice with whatever codec/format ...
You can use the Time Remapping effect, and just use keyframes to ease in/out of different speeds. https://helpx.adobe.com/premiere-pro/using/duration-speed.html
